I have an UEFI and use Windows 10. I used the "Clean" function of EasyUEFI in order to clean unused entries from my UEFI boot partition. However, this seem to damaged my UEFI somehow. I cannot longer login into my UEFI with F2. When I press F2 at boot, it says "Wait please ..." but I get directly moved to the boot loader instead into UEFI settings.

I'm sorry to hear that. Which version of EasyUEFI you are using? There is a bug in the previous 2.0 and we have dropped this feature in version 2.0.
Please accept our apologies for any inconvenience we have caused.
Could you contact your PC hardware manufacturer for support?

Sure, I added it to the post. I renamed the file extension to .txt because I was not allowed to upload .log.
To make it more clearer how my setup on this laptop looks like: I have currently Fedora 22 and Windows 10 installed as dual boot. I could access the UEFI menu with F2 without any problem before I used the clean function of easyUEFI.

Thank you for your support!
I'm so sorry, we have analyzed the log file you send to us, there is no useful data that can help us to recover the boot options which have been deleted.
Of course, if we can find the same model computer as you, then we should be able to fix it.
